Patented Dec. 3, 1929 UNITED STATES ALBERT S. KUX, OF CHICAGO, ILLINOISGLEANING DEVICE Application filed November 25, 1925.

This invention relates to improvements in cleaning devices of the typegenerally known as vacuum cleaners, and one of the objects of theinvention is to provide an improved device of this character which isparticularly adapted, though not necessarily limited in its use, forcleaning ovens such as bakers ovens and the like.

A further object is to provide an improved cleaner of this characterwhich may be employed for cleaning the oven While the latter is hot, andthe device includes improved means for handling the hot refuse removedfrom the oven, and at the same time avoid danger of injuring theapparatus and also the operator thereof.

A further object is to provide an improved portable apparatus of thischaracter which will be of a simple and compact arrangement,

eifective and eflicient in operation and readily adaptable for cleaningparts which it is ordinarily diflicult to gain access to.

To the attainment of these ends and the accomplishment of other new anduseful objects as. will appear, the invention consists in the featuresof novelty in substantially the construction, combination andarrangement of the several parts hereinafter more fully described andclaimed and shown in the accompanying drawing illustrating this invention, and in which 1 Figure 1 is a view partly in side elevation,

partly in section and partly broken away of an apparatus of thischaracter constructed in accordance with the principles of thisinvention.

Figure 2 is a right hand end elevation of Figure 1.

Referring more particularly to the drawing the numeral 10 designatesgenerally a supporting structure which may be of any desired size andconfiguration and constructed of any suitable material.

The supporting structure is preferably in the form of a truck likeformation having rear wheels 11 and a front or castor wheel 12 swiveledfor movement with respect to the su porting structure 10. En the upperportion of the supporting structure 10 is swiveled an element 13 pro-Serial No. 71,282.

vided with spaced bifurcated supports between which a tubular member 14is'disposed. The member 14 is supported by the element 13 preferably bymeans of trunnions or projections 15 on the tubular member 14 which areseated in the respective bifurcated portions of the element 13.

The tubular member 14 is of any desired length and diameter andconstructed of any suitable material, preferably metal, and connected toone end thereof is a tubular extension 16. This section 16 may besecured to the section 14 in any suitable manner preferably by means ofone end of the member 1a telescoping into the section 14 and a pin C5 17and bayonet slot connection 18 is provided for securing these partstogether.

Atthe end of the section 16 is arranged a nozzle 19 of any desiredconstruction but is preferably of a configuration to provide anelongated comparatively narrow slot 20 forming the inlet opening to thenozzle.

Brush like members 21 preferably constructed of a substantially rigidmaterial such as wire or the like may be secured to the end of thenozzle 19 and on opposite sides of the inlet opening 20 to projectbeyond the end of the nozzle for the purpose of facilitating in theremoval of any foreign matter which might adhere to the Walls of theoven, This material and the refuse in the oven may be removed from thewalls thereof or agitated by a manipulation of the nozzle within theoven. f

Suction is created in the nozzle through the tubular sections 16 and 14in any suitable manner preferably by means of a suction creating device22 in the form of a rotary fan which is arranged within a casing 23. Thetubular section 14 is preferably detachably secured to the casing23 ofthe fan 22 in any suitable manner such as by means of a pin and bayonetslot connection 2425.

The fan casing 23 is provided with a discharge outlet opening 26 towhich a container 27 is secured preferably by means of a tubular member28 to which the container is attached and which tubular element isconnected with the discharge outlet of the fan eas 100 ing preferably bymeans of a pin and bayonet slot connection 2980.

The container or receptacle 27 is preferably constructed of any suitablefabric which will permit the air currents to pass there through and isremovably secured to the element 28in any, suitable manner.

The element28 issof such a size and configuration and the supportingstructure 10 is of such a height that the bagpr receptacle 27 will besupported above the floor.

Within the bag or receptacle 27 is alstrainer or filter 31 which may beconstructed'of any suitable reticulated materialgsuchas metal,preferably in the form of wire gauze and is securedqin any:suitablemanner to the element 28.1, V

The; external :diameteryand the vlength of the; element-p31 iisconsiderably-Jess than vthe internal, diameten and the length; :of thebag orireceptacleifl andis provided for the pur? pose of not onlyserving as-a-fil-ter or strainer f r; separating the refuse and foreignparticles, fromtthe airas theyare, discharged into thebag;ori-receptacle;27, but when this impltoveduapparatusiis used forcleaning the ovens when the latteraie hot, the refuse which is.withdrawn. from: the oven is also hot, and he element 31 will confineand .hold these hot; particles,

a To discharge these hot i particles directly intoothe bag10rreceptaclel 27,w ould cause COIlSi'dBI'iblGg damage to: the bag. 7

By; pnoviding the, metal strainer on filter 3];- s'it'iwill bemanifestthat the hot particle-s willy-be confined Within; the; metallic portion31 andtheyiwill beheld, out; of contact with thebagoor receptacle 27.

Thesuction'creating device 22 may be openatediinaany suitable mannersuch as by means ofqa moton 32; which is mounted upon aisuitableisupportto movewith the tubular member: il lsand; the fan 22,-, preferably upontheifan .Ci Sin-g', the shaftBB-of. the motor eX- tcndingi thnoughvthewall of the fan casing I spacing blocks or velelnentsaiil' constructedof i -ply (notashown y Handles; 38 and39 may be connected with theapparatus for facilitat ing in manipulating the same.

Obviously any number of sections 14: and 16 may be provided anddetachably connect ed together in any suitable manner so as to lengthenor shorten the same.

The nozzle 195-is also. detachably secured to the; section-41 6 in anysuitable manner.

In use it Will be manifest that by means of the handles 38 and 39 theapparatus may be swung about'the pivots 15 and also may be rotated on avertical axis through the medium of the swivel connection of the element13 :withxth6:supponh1,0. The castor 12 being swiveled to the support 10also facilitates in; the manipulation of the device.

When the suction creating; device 22 is in; operationiand whenthenozzle19 is inserted in; the oven; the operator may move the inlet ;endofjthe nozzle over; the surface of the ovenntoascrape cr -removeforeignparticles from the-wall of theovenandwwhen theisuction creating device22 operatesfther foreign matterwill beidrawn into the-nozzle throughthee fan casing; and {discharged through the element 28 into themetallic filter or strainer- 31vvhereitwill be confined! Theeaircurrents will pass, out of the filter :or: strainer .31 and into the bag27 .to be discharged :therefrom through the walls. ofthe-latter.

While this improved apparatushasbeen used-for many-other punposesandforcleaning parts to1whichiordinarily access may not be readily hftd'.:,

Obviously this device may beused for. removing; foreign? matter fromflues, i and if desired; the nozzle; 19, may; be removed and any other;form I of nozzle --may :be attached tort-he section 16 or the-endiofthesection 16 may be allowed to remain-open whenthe dc vice is-nsedq forcleaning flues,

WVhile thekpreferred form of, the invention has been-herei11;shownanddescribed it isto be understood that various changes maybe made in lthe; details of construction and in he -;combina.tion and arrangement ofthe "several parts, within the i scope: of r theclaims, withoutdepanti-ngzfrom'thespirit of thisinvention.
